Feature Article

Targeted Shoulder Exercises Improve Function and Reduce Surgery for Subacromial Impingement Syndrome

 

Impingement syndrome is a common shoulder ailment causing pain and loss of function. Usual treatment includes steroid injections and physical therapy, but treatment failure is common, and as a result, nearly a third of patients may eventually have arthroscopic decompression surgery. A recent randomized trial evaluated the efficacy of an exercise program targeted to improve function and reduce the need for surgery in 102 patients with persistent subacromial impingement syndrome that was unresponsive to conservative treatment.

 

Patients (mean age 52 years) with symptoms for > 6 months who were on a waiting list for arthroscopic surgery were randomized to 1 of 2 supervised exercise programs for 12 weeks. The specific targeted exercise program included eccentric strengthening exercises for the rotator cuff, concentric and eccentric strengthening exercises for the scapula stabilizers and manual mobilization. The control program included general movement exercises for the neck and shoulder. All patients had a subacromial corticosteroid injection 2 weeks prior to initiating exercises, education on ergonomics and posture, individual physical therapy and a home exercise program.

 

At the end of treatment, the targeted exercise group had a significantly higher rate of patients reporting either recovery or large improvement in symptoms (69% vs. 24%, p < 0.001, NNT 3) (level 1 [likely reliable] evidence). Surgery was performed on 20% of the targeted exercise group vs. 63% of controls (p < 0.001, NNT 3). Targeted exercise was also associated with significantly improved health-related quality of life. There were no significant differences in the use of analgesic or anti-inflammatory drugs (BMJ 2012 Feb 20;344:e787). A data supplement to the article includes instructions for the exercise program (PDF).

New Cervical Cancer Screening Guidelines Recommend Less Frequent Screening

 

New recommendations for cervical cancer screening from the United States Preventive Services Task Force (USPSTF) (Ann Intern Med 2012 Mar 14 early online full text) and from the American Cancer Society, American Society for Colposcopy and Cervical Pathology, and American Society for Clinical Pathology (ACS/ASCCP/ASCP) (CA Cancer J Clin 2012 Mar 14 early online full text) were published in March. Both statements recommend cytology screening beginning at age 21 years for women at average risk (women who are not immunocompromised and have no history of cervical cancer or in utero exposure to diethylstilbestrol). Cytology (Pap smear or liquid-based cytology) is recommended every 3 years for women through age 29 years. For women aged 30-65 years, the screening interval can be extended to once every five years if co-testing with both cytology and human papillomavirus (HPV) testing is used (or once every 3 years for cytology alone). Both groups recommend no screening for women > 65 years old who have adequate prior negative screens.
